Abstract: A microelectromechanical system (MEMS) strain gauge pressure sensor includes a top wafer stack having a top surface and a first cavity that is configured to receive a first fluid at a first pressure, a backing wafer having a bottom surface opposite the top surface of the top wafer stack; a diaphragm wafer positioned between the top wafer stack and the backing wafer and having a second cavity that is configured to receive a second fluid at a second pressure, and a pedestal connected laterally to the top wafer stack, the backing wafer, and the diaphragm wafer. The diaphragm wafer includes a diaphragm extending between the first cavity and the second cavity, and a resistor positioned on the diaphragm. The MEMS strain gauge pressure sensor has a central axis such that the MEMS strain gauge pressure sensor has mechanical symmetries about the central axis.

Abstract: A head-mounted display includes a main body, an operation unit, and a controller. The main body includes a display unit capable of displaying an image in front of an eye of a user. The operation unit includes a buffer that is connected to the main body and deformable with respect to the main body, and a first detector configured to output a detection signal depending on the deformation. The controller is configured to generate an image signal for generating an image based on the detection signal and to output the image signal to the display unit.

Abstract: A coordinate input device comprises a base (10) having a plate shaped distortion generating part (12) below a pole shaped operating part which are integrally formed; and a detection sensor (20) having a plurality of distortion gauges (22) (four) and a plurality of leads (23) connected to the distortion gauges which are integrally arranged on one plastic sheet (21). In the coordinate input device, the plurality of distortion gauges (22) are put together in the arrangement of a cross shape so that the distortion gauges are bonded at prescribed positions on the back surface of the distortion generating part (12) by using a cross index (25) which is previously attached to the sheet (21). The plurality of leads (23) are arranged in parallel and extended sideward the base (10). Accordingly, a workability and accuracy in assembly can be improved and the operating part can be made compact without increasing the burden of cost or deteriorating installation workability.
